President Obama is expected to outline his national security and foreign policy achievements in Tuesday's State of the Union address. He recently told Time Magazine it's "pretty hard to argue" that his administration's strategy over the last three years "has put America in a stronger position than it was when we ... came into office." Do you agree? What have been this administration's biggest national security achievements? What needs work? What should be this administration's national security priorities for the coming year?

A new round of proposed sanctions targeting Iran's central bank and oil exports to Europe have caused a devaluation of the Iranian currency and a sharp spike in inflation, provoking Iran to threaten to close the Strait of Hormuz and choke off 20 percent of the world's oil supply. Meanwhile, another Iranian nuclear scientist was assassinated this week in what is increasingly looking like an undeclared, covert war between Iran and US ally Israel, even as Iran announced a new uranium enrichment site at a heavily-defended and buried nuclear facility near the holy city of Qom. Will these growing pressures and tensions eventually lead to an outright military conflict between Iran and the U.S. or its allies? If such a conflict starts, should the U.S. use it as an opportunity to strike Iran's nuclear complex militarily to set back its suspected nuclear weapons program? How likely is it that the pressures will finally prove strong enough to force Iran to negotiate away its nuclear weapons program?

President Obama's new defense strategy moves the Pentagon beyond Cold War-era ground wars and post-9/11 counterinsurgencies and into an envisioned era of joint air and naval conflicts with nations like Iran or China, and perpetual readiness to attack global terrorism with flexible and futuristic asymmetric capabilities. Doing so will require shifts and cuts in weapons procurement, significant cuts to the size of the Army and Marine Corps, and reducing Cold War-era programs like nuclear deterrence. What part of the review was most salient, and what was missing?

The U.S. military closed its Baghdad headquarters last week, formally marking the end of the war as the remaining 3,500 troops leave the country. After nearly nine years of war, nearly 4,500 American troops killed, 30,000 wounded, and nearly $1 trillion spent--and possibly over a hundred thousands of Iraqis dead and millions displaced within the country and abroad--will Iraq's security forces be able to maintain security within and on its borders? What role if any will the U.S. have in Iraq's future security? What is the greatest challenge Iraqis will face in the next year?

Defying a White House veto threat, the Senate adopted controversial detainee provisions within the defense authorization bill last week that would require mandatory military detention for some terrorism suspects. Do you agree with the administration and a slew of law enforcement, intelligence, and Pentagon officials who argue the provisions reduce their flexibility in handling the war on terror? Or do you agree with the Senate Armed Services Committee leadership who insist the provisions merely "codify" existing procedures? Will the White House veto the bill? Should the waiver be enough to assuage administration concerns? Is this a discussion suited to the Senate floor during debate of the defense authorization bill, or should it have taken place at a different time?

Last week, U.S. officials announced new steps for a strategic "pivot" to Asia and the Pacific that included plans to deploy 2,500 troops to a base in Australia's northwest outback and "unprecedented" initiatives to build alliances and agreements across the region. How much of this has to do with China? Should the U.S. move even more troops to the Asia-Pacific region? Or, should there be an entirely new Pacific realignment? Beyond rhetoric, what else will be required for the U.S. to make this pivot?

On Nov. 12, National Journal and CBS News are hosting a Republican primary debate focusing on national security and foreign policy. What should the moderators ask the GOP presidential candidates? How would you rate the contenders' performances on national security and foreign-policy issues during their respective campaigns? In judging the candidates' fitness for the presidency, how important is experience in these issues? In your opinion, is there one candidate who's emerging as the best nominee, based on foreign-policy and national-security issues alone? Please weigh in on these or any related topics.

Two days of meetings between North Korean and U.S. official in Geneva this week did not produce an agreement to formally resume negotiations-- either bilaterally or in the so-called six party talks-- about possible steps toward Pyongyang's denuclearization. When Defense Secretary Leon Panetta was asked in South Korea whether he thinks a renewed U.S. push to explore negotiations will work, Panetta said: "We're not sure where those talks are headed at this point. For that reason, I guess the word 'skepticism' would be in order."

Do you believe engagement with North Korea to reach a diplomatic solution should continue? What can it reasonably be expected to achieve? Does the periodic failure of the diplomatic track allow the U.S. to keep sanctions and pressure on Pyongyang? What more should the U.S. do to pressure Pyongyang? Is there anything China can be expected to do that will push North Korea to give up its pursuit of nuclear weapons? Also, how much should the world worry that an accidental confrontation between North and South Korea sparks a broader conflict?

The Obama administration is looking to further isolate Iran after last week's announcement that the elite Quds Force was allegedly behind a plot to assassinate Saudi Arabia's ambassador to the U.S. and bomb the Saudi and Israeli embassies. What more can-- or should-- the administration do to tighten the financial vise around Iran? Have the administration's efforts in recent years made a difference in deterring Iran's nuclear program and thwarting international terrorism? Were the additional sanctions levied this week an adequate response to the plot? Should other options outside sanctions be considered?

The 10th anniversary of the war in Afghanistan passed quietly at the White House last week. With the U.S.-led coalition slated to hand over security responsibility to the Afghans by 2014, American military commanders have stressed that battlefield progress in the country remains "fragile and reversible." Optimism that Taliban leaders will ever join in the peace process has hit a new low with the recent assassination of the country's top peace negotiator, former President Burhanuddin Rabbani. Will Afghanistan be ready to take control of its own security? What happens if the country returns to full-blown civil war after American troops pull out?
